In the present scenario of automobile sector, auto rickshaws (3-wheelers) are the most sought after public transport among the urban and rural poor in India. Majority of people depend on these vehicles after public transport systems like Road Transport Corporation. Among these 3-wheelers, 7-seaters are the most popular and a lot of developments are seen in the past few years. MLR Motors Pvt Ltd, Hyderabad is a 3- wheeler manufacturer which is trying to mark its presence in the market. "TEJA" The vehicle manufactured by the company has a seating capacity of seven persons including the driver. The vehicle has a worm and roller type steering gear mechanism unlike other conventional auto rickshaws fitted with handle bars. Manufacturing of an auto rickshaw involves assemblies of several major components. L-Angle of the auto rickshaw is one such major component. It connects the floor and front panel and plays a vital role in design and development of the vehicle.

The project work deals with modeling and analysis of the L-angle, subjected to structural loads. The analysis is carried out to optimize the L-angle by analyzing the behavior of the L-Angle for varying thicknesses, different materials and modifications in design. The modeling of L-angle is first carried out in CATIA V5 R18 using Part Drawing and Surface Modeling module. The analysis is done using ANSYS 11.0 by importing the solid model from CATIA in IGES format. During the static and modal analysis the model is subjected to various loads, the results are derived and the optimized L-angle is proposed.
